Usage

asem(
  Loo,
  K,
  t0 = -0.5,
  aW = 0.01,
  bW = 3.04,
  Lm,
  dLm = NULL,
  tmin = 0,
  tmax,
  h,
  M,
  Lc = NULL,
  dLc = NULL,
  Fvec = NULL,
  R0 = 1
)

Arguments

Lm	length-at-50-maturity (cm)
dLm	width of ogive (default=0.1*Lm)
tmin	minimum age
tmax	maximum age
h	steepness of B&H SSR
M	natural mortality
Lc	length at first capture
dLc	width of ogive (default = 0.1*Lc)
